Setting this object causes the specified filename to be deleted, after first validating that the authentication data is correct for the specified user ID. The format for this object is a C structure: typedef struct { sint32 UserId; uint16 AuthenticationDataLen ubyte AuthenticationData[] char Filename[]; } fs_delete_files_t; which is described below: Bytes 0 - 3: contains a user id represented as a multi-byte value that is stored in big-endian format, where the most significant byte occurs first. Bytes 4 - 5 : Length of the Athentication data that follows starting at offset 6. Stored as a multi-byte value that is stored in big-endian format, where the most significant byte occurs first. Bytes 6 - 6+AuthenticationDataLen : a ubyte array containing the Authentication data used to verify MAX-ACCESS for this operation. Bytes starting at offset (6+AuthenticationDataLen+1): A null terminated character array representing the ASCII file name to be deleted. The length of the string will be limited by the remaining space in the object. This string represents a fully-qualified path name which may specify a filename or a regular expression that may match multiple files (e.g <path>/*.exe). Access to this command is controlled by the UserId and the authentication data. If the UserID or authentication data supplied is incorrect the command will fail. The device POS will specify any limitations to the length of the filename string, what constitutes a correct user ID, what constitutes correct authentication data, and the significance of any return values. Additional information: Setting this object causes the specified filename to be deleted, after first validating that the authentication data is correct for the specified user ID.
